Question

我想对内部查询的结果进行GROUP BY ACCOUNTNO。

SELECT * 
FROM (SELECT O.CUSTADDRESSID, O.ACCOUNTNO, D.ORGANISATIONNAME
      FROM db.sc.TP_CUSTOMER_ADDRESSES O FULL OUTER JOIN
           db.sc.TP_CUSTOMER_BUSINESS D 
      ON O.ACCOUNTNO = D.ACCOUNTNO
     ) a 
GROUP BY ACCOUNTNO 
ORDER BY ACCOUNTNO;

但是我收到此错误：

信息8120，第16级，状态1，第1行
选择列表中的“ a.CUSTADDRESSID”列无效，因为它既不包含在聚合函数中，也不包含在GROUP BY子句中。

需要帮助。谢谢。

Answer 1

您需要删除“ GROUP BY ACCOUNTNO”-查询如下：

SELECT * FROM (SELECT
   O.CUSTADDRESSID, O.ACCOUNTNO,
   D.ORGANISATIONNAME
FROM
   db.sc.TP_CUSTOMER_ADDRESSES O    FULL OUTER JOIN db.sc.TP_CUSTOMER_BUSINESS D ON O.ACCOUNTNO = D.ACCOUNTNO) a 
ORDER BY ACCOUNTNO

或列出分组依据的所有列-查询如下：

SELECT * FROM (SELECT
       O.CUSTADDRESSID, O.ACCOUNTNO,
       D.ORGANISATIONNAME
    FROM
       db.sc.TP_CUSTOMER_ADDRESSES O    FULL OUTER JOIN db.sc.TP_CUSTOMER_BUSINESS D ON O.ACCOUNTNO = D.ACCOUNTNO) a 
    GROUP BY ACCOUNTNO, CUSTADDRESSID, ORGANISATIONNAME
    ORDER BY ACCOUNTNO

Answer 2

“分组依据”和“选择分组”不相同，这是一个示例：

SELECT ACCOUNTNO, CUSTADDRESSID, ORGANISATIONNAME FROM (
  SELECT
   O.CUSTADDRESSID, O.ACCOUNTNO,
   D.ORGANISATIONNAME
   FROM
   db.sc.TP_CUSTOMER_ADDRESSES O    FULL OUTER JOIN db.sc.TP_CUSTOMER_BUSINESS D ON O.ACCOUNTNO = D.ACCOUNTNO
   ) a 
 GROUP BY ACCOUNTNO, CUSTADDRESSID, ORGANISATIONNAME  ORDER BY ACCOUNTNO

内部查询结果的GROUP BY无法正常工作
